United States Patent "ms invention relates t6 agricultural implementsand niore'par't-icularly'to j Ari dbjec't' of the in eritioii toprovidea side delivery'hay rake that evil g m swath on the groundafterwithout scattering the leaves a'rid leave? a windrow'. The sine"delivery hayi'rake' may'also used to" ti'l'r'n windr'owd say or grainfor drying.-

Briefiy, the side delivery hay rake is front end of any tractor and asthe ward the hay will force its way up aiid 'ver to be disounted at thetines; They are made of spring metal, for, example spring steei and arefastened at their lower end behind'the' front so that the hay will nothave any place to catch onto. A portion of each tine contacts the groundto keep the front of thetine from digging into the ground.

Accordingly, another object of the invention is to provide a hay rakewith what is considered to be a unique tine configuration to improve thehandling of hay, grain and the like as it is turned or otherwise movedduring normal farming operations.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure l is a fragmentary top plan view of a conventional tractorequipped with a side delivery hay rake constructed in accordance withthe invention.

Figure 7 is a sectional view showing a modification of one of the framemembers.

In. the accompanying drawings there is shown a conventional tractor 10which diagrammatically represents any manufacturers make or type oftractor with which a side delivery forward mounted hay rake may be used.

the" the a moves forn important feature of the invention. is foundin theHay rake 12 is shown mounted 'at the front of tractor 10. The hay rake12 is one exemplifying embodiment 1 figs-mam; am the inner nds meteoric.the arias closest to tractor I0, have upstanding frame member 24 fiXdthereto by conventional fastening niea intranet; wens 26. 4

of id'ent'ical mounting brackets 28 and 30 are used to connectth'upstanding Eran-lb members 22' and 24 to the s ides of the tractorne'a'r are front thereaf- The mounting brackets consist of mountingplates 36 and 38 connected by bolts 40 or the like to the' trans 1 1 oftractor 10. There are a or spindles 46 and 48' which are fixed to themou ting brackets 38 and as by welds 50, and the spindles are coaxialand' horizontai when the tractor is resting on a horizon l sa r e'e.Spindles 4s and 46 extend threu' nssenures 547 in the upstanding framemembers 22' are 24; and there is a fastener, for instance, cotter'ky 56at end of each spindle preventing the framer'neinbers from slldingtherefrom. The spindles, mountin'g brackets amt apertures iii theupstanding frame me'r'nl")'ers' 22 and 2'4 mount the frame of the hayrake 12 for pivotal msve: men about the longitudinal of spindl'es" 46and 48.

In order to pivotally actuate the frame or the hay rake" andeonse nentlythe entire hay rake, conventional means are operatively connected withthe frame of the rare: These conventional means are shown as hydrauliccyl inders 60 pivoted at one end onbrackets 62 which are welded as at,63 or otherwise secured to 5 framejmembe rs 22, 24. The opposite endsofthe,hydraulic cylw inders are pivotally connected to depending brackets64 attached to the tractor frame 11. The hydraulic system of the tractoris operatively connected to the hydraulic 68 and 70 are passed throughaligned apertures in the frame members 18 and 20. It is pointed out thatthe specific means for fastening together the various parts may bevaried without departing from the invention.

Attention is now invited principally to Figures 4, 5 and 6. These showthe construction and shape of the tines of the rake 12 and the way thatthey are preferably attached to frame members 66 and 16. Typical tine 80is made of spring steel or other metal and has a smoothly curved arcuatepart 82 with an upstanding end 84 which is very short in comparison tothe length of the arcuate part 82. The arcuate part has a lower end 85which is bent at 180 so that part 86 of the tine is parallel thereto forshort distance. Continuing toward end 87, the tine has 'a slightdownwardly curved portion 88 and then an upwardly curved portion 89 atthe end of which there is a short straight extension 90. End

87 projects upwardly at right angles to the short straight of framemember 66 and is held in place by means of a a U-bolt 94, hook or thelike which is attached to flange 67. End 87 extends through an aperture95' in the lower flange of frame member 16, and the straight portionfits flush against the bottom surface 96 of the lower flange of framemember 16. A hook 97, or the like extends through aligned apertures inthe upper and lower flanges of frame member 16 and has thecurved part98' thereof engaged around the straight part 90 of the tine.

The tines are oriented in parallel relationship, and l the end portions85 project forwardly (see Figure 2).

The curved parts 8% are ground engaging. They ride along the surface ofthe ground to prevent the ends 85 from digging into the ground.

The preferable mounting for the rake 12 is to have it as a side deliveryhay rake at the front of a tractor. Accordingly, it is arranged so thatthe frame members and tines are at an angle to the longitudinal axis ofthe tractor iii so that the hay rake will be capable of windrowing orturning material in a windrow. The material, for instance, hay, grain,etc. rides up the inclined part of the tines of the hay rake that is,the lower parts of the smoothly curved portions 82 and in riding up, thematerial turns over upon itself thereby continually rolling as thetractor moves forward. Wheels on member 16 can be used for addedsupport.

Figure 7 is a sectional view showing a modification of the frame member16. The modified frame member 16a is a box beam having aligned apertures13% and 131 in the front and rear walls 132 and 133 thereof. Tines 8th:differ from tines 89 by having the ends 94% extended through apertures131i and 131 and parts 87 of tines $9 omitted. Cotter pins 137 or thelike are used to retain ends 9 in member 16a.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. In a side delivery hay rake, the combination of spaced upper andlower horizontal frame members disposed in parallel relation with theupper member spaced forwardly from the lower member, and a set of spacedparallel tines carried by said frame members, each of said tinesincluding a vertical upper end portion secured to the upper framemember, a relatively long curved intermediate portion extending firstrearwardly and then downwardly and forwardly from said upper end portionto a point below and forwardly of the lower frame member, 21 reverselybent portion provided at the lower end of said curved inter-mediateportion, a curved lower portion extending first rearwardly anddownwardly and then upwardly from said reversely bent portion, and alower end portion on said curved lower portion secured to said iowerframe member.

2. The device as defined in claim 1 wherein said curved lower portion isadapted to engage the ground at a point below the lower end of saidarcuate intermediate portion, whereby said lower end of the intermediateportion is spaced upwardly from the ground.

3. The device as defined in claim 1 together with clamp means providedon said upper and lower frame members and securing said upper endportions and said lower end portions, respectively, of said tinesthereto.
